Changing a combox on WindowsForm

[CaptainBeardsEyesBeard]

Previously I changed a combo box (for another program) 

Local $hWnd3= WinWait("[CLASS:ProMainWin]", "", 10)
$hComBo1=ControlGetHandle($hWnd3, "", "ComboBox4")
Sleep(1000)
_GUICtrlComboBox_SetCurSel($hComBo1, 35)

However I googled autoit combo boxes and came across about Windows Forms (which I assume is what I'm dealing with given the control class) and tried it this way which was the answer after googling. 

; ---------------------------------------------------------------------------
        ;Action: Change Combo box to "Elite Matter Number" 
        $hComBo1=ControlGetHandle($hWnd, '', 'WindowsForms10.Window.8.app.0.338574f_r42_ad112')
            if @error then 
                Msgbox(16, "Error", "Cannot ControlGetHandle the dropdown combox to select Elite Matter Number") 
            endif
        Sleep(1000)
        ;_GUICtrlComboBox_SetCurSel($hComBo1, 6)
        _GUICtrlComboBox_SelectString($hComBo1, "Matter Management - Elite Matter Number (File Cover) (FCO06)")
                if @error then 
                    MsgBox(16, "Error", "Cannot select Combo box") 
                EndIf
        ; ---------------------------------------------------------------------------

It quits the program though and outputs this at console 

$hComBo1=ControlGetHandle($hWnd, '', 'WindowsForms10.Window.8.app.0.338574f_r42_ad112')
$hComBo1=ControlGetHandle(^ ERROR
>Exit code: 1

I wonder why it doesn't trigger the if @error statement and just ends?

@CaptainBeardsEyesBeard

first i dont see $hWnd var ,but this:

Local $hWnd3= WinWait("[CLASS:ProMainWin]", "", 10)

should be:

 

Local $hWnd= WinWait("[CLASS:ProMainWin]", "", 10)

Trying to control a windows 10 form isn’t going to work in native auto IT  it’s not a win32 form nor are the controls win32

you can use UIAutomation
